安装therubyracer时无法构建gem本机扩展

Question

我想知道我将uru与两个版本的Ruby一起使用可能会有所帮助，因为nogokiri gem不支持ruby 2.2。 我也不知道为什么为什么要说一些关于python的信息（我安装了3.4.3 python）

C:/Ruby21-x64/bin/ruby.exe extconf.rb

Answer 1

从错误消息：

libv8需要python 2

从您的帖子中：

我已经安装了3.4.3 python

Python 2！= python 3。

Answer 2

我无法确定您的路线，但是您是否尝试过将Devkit用于RubyGems ？ 我记得当我在Windows机器上使用Ruby raw时，这非常轻松。
